Title: Calibration of liquid scintillators
Inventor: ALOIS HOEGL DR-ING
IPC: G01T1/204
Filed: 1969-03-18
Abstract: To eliminate the dependence on the height of filling of the liquid in its sample flasks when determining the performance index using an active standard radiation source near the flasks and counting the supplementary scintillations as the scale of the performance index. The energy level of the source is so chosen that the radiation is largely absorbed by the scintillator liquid. It is located in such a way relative to the sample flask during measurement that the beam passes through the liquid from above. The supplementary scintillations used to measure the intensity of scintillation light are taken only from a portion of the fluid neat the bottom of the flask and from over 5-30% of total height.

Patent DE-2154620-A1 (DE)
Title: Protecting glasswear
Inventor: SHANK JUN HERBERT C
IPC: B29C35/04
Filed: 1971-10-29
Abstract: A glass article is protected in at least the bottom region of its side walls and part of its base by a heat shrunk sleeve of thermoplastic material. The material may be P.V.C., polyethylene, polypropylenen or polyethylene terephthalate and is initially in the form of a loose fitting tubular film. The heat shrinking may be effected under reduced pressure in a heated chamber or by immersion in hot water. Bottles may be coated in this manner, and it is possible, due to the enhanced protection afforded by the shrunk film, to reduce the thickness of the bottle at the peripheral regions of its base, thus reducing production costs.

Title: Roofing felt - heat-bonded at overlaps
Inventor: KOHLENBECK HELMUT
IPC: B32B27/00
Filed: 1972-02-29
Abstract: The felt core consists of ethylene copolymer, a small quantity of bitumen, anthracite dust and high pressure polyethylene, and is faced with glass fibre mat, except along a longitudinal edge strip where it is laid to overlap the adjacent felt.

Title: Air cooled blown plastics tube - simultaneously calibrated by passing through series of annular discs
Inventor: WEINERT MANFRED DIPL PHYS DR
IPC: B29C48/90

Title: Water boiler thermostat sensitive to steam temperature - is insulated from steam pipe by insulating sleeve
Inventor: APPUN ERNST
IPC: F24H9/20
Filed: 1973-08-02
Abstract: The thermostat is a high level one which is to operate when generated steam enters the pipe. To react immediately to steam temperature it has to be insulated from heat conducted through the pipe. The steam pipe is surrounded by a silicon rubber sleeve which has a transverse passage over a hole in the pipe. The passage is closed by a metal plate to which the temperature sensitive element is connected. The sensitive element is thus shielded from heat conducted through the pipe wall whilst being exposed to the temperature of the steam.
